Here is some description of major changes coming in RHEL 7 than RHEL 6. This list doesn’t contain all the changes available in RHEL 7.

    GRUB2 Configuration File: /boot/grub2/grub.cfg

    3. New Init System

    As we know RHEL 6 and older releases used SysV init system. But RHEL 7 has been released with new init system systemd which is compatible with SysV.

    4. New Installer

    Red Hat Enterprise Linux 7 has and redesigned Anaconda version. Which have many improvements in system installation.

    5. Changes to firstboot Implementation
